Mr. King was the manager（經(jīng)理）of a hotel．One weekend all the hotel in the city were full because there was a large meeting．On Friday night，three men came into the hotel and asked for rooms．Mr. King said there were no rooms ready because of the meeting．The men were unhappy．

Mr. King wanted to help them．He remembered that Room 418，a very small room，was empty．He asked them if they would share a room．The three men said they would．Mr. King said the room would be thirty dollars：ten for each one．Each man gave the money and then went up to the room．

Mr. King Soon began to feel sorry．“Thirty dollars is a lotto ask as price for that small room．” He thought．He called his assistant over and said，“Here is five dollars．Take it to the men in Room 418．I asked too much for their room．”

The assistant took the money．While he was on the way there，he started to think，“How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself．The men will be happy to get something back，and Mr. King will never know．” So the assistant returned one dollar to each man．

Each man had at first paid ten dollars．After the assistant returned them one dollar each，each had paid nine．There were three men，$9×3=$27．The assistant kept $2．$27+$2=$29．Where is the missing dollar?

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have traveled to the places, you can go and see a colour film about them, or you can read a travel book.
It seems that there are three kinds of travel books. The first are those that give a personal, subjective(主觀的) idea of travels which their writer has got himself. These books can be useful if the writers share their traveling experiences with others. The second kind are those books which give objective(客觀的) information of things to be done and seen. If a cultured personhas written such a book about the facts of a place, then it is more useful. The third kind are those books which are called “a guide” to some place or other. If they are good, they will describe and explain the place in detail. Like the first kind , they can be interesting and exciting, but their main purpose is to help the reader plan his travel in the most practical way.
Whatever kind of travel book you choose, you must make sure that the book does not describe everything as interesting, exciting or fantastic. You must also keep an open eyes on its date of publication(出版) because travel is very practical matter and many things change quickly in the 21st century. Finally, you should make sure that it’s easy to find the useful information for your travel.
